2. The central entity of claim 1, wherein the updated transport network layer information further identifies an Internet Protocol (IP) prefix associated with the at least one of the IPv4 address or the IPv6 address.

3. The central entity of claim 1, wherein the change of the first donor distributed unit to the second donor distributed unit comprises redirecting an existing control interface association or tunnel from a route associated with the first donor distributed unit to a route associated with the second donor distributed unit.

4. The central entity of claim 3, wherein the first donor distributed unit is associated with a first central unit and the second donor distributed unit are associated with a second central unit.

5. The central entity of claim 1, wherein the updated transport network layer information is associated with the second donor distributed unit.

6. The central entity of claim 1, wherein the one or more processors, to determine that the trigger condition is satisfied, are configured to determine that the trigger condition is satisfied further based at least in part on receiving an indication from a mobile terminal of the IAB node or a different IAB node associated with the central entity.

7. The central entity of claim 1, wherein the one or more processors, to determine that the trigger condition is satisfied, are configured to determine that the trigger condition is satisfied further based at least in part on receiving an indication from a distributed unit of the IAB node or a different IAB node associated with the central entity.

8. The central entity of claim 1, wherein the updated transport network layer information is provided using a radio resource control message.

11. The central entity of claim 9, wherein the information associated with the at least one of the IPv4 address or the IPv6 address indicates a usage for the at least one of the IPv4 address or the IPv6 address, and wherein the updated transport network layer information is based at least in part on the usage.

12. The central entity of claim 9, wherein the information associated with the at least one of the IPv4 address or the IPv6 address does not indicate a usage for the at least one of the IPv4 address or the IPv6 address, and wherein the updated transport network layer information is used for all traffic based at least in part on the information associated with the at least one of the IPv4 address or the IPv6 address not indicating the usage.

13. The central entity of claim 1, wherein the change of the first donor distributed unit to the second donor distributed unit is associated with radio link failure of a mobile terminal.

14. The central entity of claim 1, wherein the first donor distributed unit and the second donor distributed unit are associated with a same central unit.

15. The central entity of claim 1, wherein the signaling service comprises F1-C traffic and the data transport comprises F1-U traffic.

16. The central entity of claim 1, wherein the trigger condition is determined to be satisfied further based at least in part on receiving an indication from a distributed unit of the IAB node or a different IAB node associated with the central entity.

20. The IAB node of claim 18, wherein the information associated with the at least one of the IPv4 address or the IPv6 address indicates a usage for the at least one of the IPv4 address or the IPv6 address, and wherein the updated transport network layer information is based at least in part on the usage.

21. The IAB node of claim 18, wherein the information associated with the network address does not indicate a usage for the at least one of the IPv4 address or the IPv6 address, and wherein the updated transport network layer information is based at least in part on the information associated with the at least one of the IPv4 address or the IPv6 address not indicating the usage.

22. The IAB node of claim 17, wherein the change of the first donor distributed unit to the second donor distributed unit is associated with radio link failure of a mobile terminal.

24. The method of claim 23, wherein the change of the first donor distributed unit to the second donor distributed unit comprises redirecting an existing control interface association or tunnel from a route associated with the first donor distributed unit to a route associated with the second donor distributed unit.

25. The method of claim 24, wherein the first donor distributed unit is associated with a first central unit and the second donor distributed unit are associated with a second central unit.

26. The method of claim 23, wherein the updated transport network layer information further includes an Internet Protocol (IP) prefix associated with the at least one of the IPv4 address or the IPv6 address.

27. The method of claim 23, wherein the first donor distributed unit and the second donor distributed unit are associated with a same central unit.

28. The method of claim 23, wherein the updated transport network layer information is provided using a radio resource control message.

29. The method of claim 23, wherein determining that the trigger condition is satisfied is further based at least in part on receiving an indication from a mobile terminal of the IAB node or a different IAB node associated with the central entity.
